Serial No. 589,672. (No model.)

T 0 all tlf-72,0771, '1125 may con/cern.'

Be it known that I, FRANKLIN EMERSON HUMPHREYS, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented a new and useful Improvement in Fireplaces, of which the following is a specification.

My invention is an improvement in heating and Ventilating devices, and has for its objects, among others, to utilize or conserve practically the entire heat produced by the combustion of fuel in open fires, to eifect a proper circulation of the currents of warm air and an equal distribution of the heated air, both in the room where the iire is located and in lateral or upper rooms to which the heat may be conveyed, and qto avoid other objections to the common open re and render its use practicable as a heating medium.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure l is a vertical section of a chimney and fireplace constructed according to my invention. Figs. 2 and 3 are cross-sections on, respectively, lines 2 2 and 3 3 of Fig. l. Fig. 4 is a detail View of the oxygen-burner, and Fig. 5 is a detail view illustrating` a form of devices for taking in air on the Windward side.

The chimney A may be of brick or other suitable material and may be in its general features of ordinary construction, being suitably enlarged at its lower end to receive the portions constituting the replace proper, in which the grate or other suitable heating medium may be properly supported.

The ireplace B may be of metal, as preferred, or it may be formed of brick or other suitable material, and from its upper end the smoke-fine O extends up through the chimney, as shown. The space within the chimney surrounding the smoke-flue C forms the hot-air flue or flues. I/Vhen but a single hotair flue is desired, this space in the chimney may be an annular one extending entirely around the smoke-Hue; but when two or more rooms are to be heated and it is desired to have a separate hot-air iue leading to each I provide vertical partitions D, which divide the space in the chimney into separate air-iiues which may lead to their respective rooms.

In Fig. l I show two rooms to be heated, the upper one E receiving air at e from its hot-air flue, the discharge of such air being controlled by a register e', which may be of ordinary construction. This register e' is shown near to the floor of the room E. The lower room F, being the one in which the fire is located, has the register]a located near the ceiling, and it is manifest that these registers e andf may be located in such manner as to secure the best results in ventilation. Immediately above the registers of the several hot-air lues I arrange diaphragnis G, closing such iiues and preventing the hot air from passing above the said registers.

The fireplace B may receive a grate, andirons, or other suitable heating medium, and immediately in rear of such place I arrange the hot-air space B', which is deflected forward toward the upper end of the fireplace at and then rearwardly at b and communicates at its upper end with the several hot-air iiues. This hot-air space or chamber B is located at the rear of the fireplace and may communicate with lateral air-heating chambers B2 at the opposite sides of the fireplace, and the front flue may be extended downward at D to form of itself a heating-surface to receive the direct heat from the heating medium, as may be desired. In supplying the fresh air to the heating space or chamber B/ it is preferred to form a fresh-air flue H,eXtending downward within the chimney alongside the smoke-flue and communicating at its lower end with the heating-chamber B', being divided from said heating-chamber by a course of bricks II or other suitable non-conducting material. It will be seen that the fresh-air flue II communicates at its lower end 7L with the air-heating chamber B. While this construction for supplying fresh air to the chamber B may be preferred, air may be supplied at h in other suitable manner without departing from some of the broad principles of my invention.

The inlet for fresh air to the fresh-air flue IOC) bustion may be furnished at the bottom of the replace and is preferably effected by a flue I, which leads from the outer air t0 what for convenience of reference l term the oXy gen-burner J, which is arranged below the grates or andirons and is composed of an upper section J and a lower section J2, the lower section J 2 being provided with a concave top plate b7'2 and an opening j through the same. The upper section J consists of a horizontal perforated tube j and a short vertical tube l7'4, communicating with the tube j and depending therefrom and arranged at its lower end to move into and out of register with the opening js of the concave plate y2, and to the lower end of the tube j is fixed a convex plate js, which coincides with and iits upon the concave plate l7'2 of the lower section. This upper section J is movable upon the lower section, so it may be set to communicate with and receive the fresh air from the opening` in said lower section or to close such opening entirely or partially to either shut off or regulate the supply of fresh air, as may be desired. At its top the upper section J is provided with projecting arms K, which project through the bars of the grate and operate to clearsuch grate as the burn er-section is swung back and forth.

The tube j rests in bearings, as indicated in dotted lines, Fig. 4, and may be rocked therein to set its lower inlet-opening into or out of register with the opening jg, which movement may be effected by any suitable handle or lever devices.

In the use of old grates or at other times when desired the oxygen-burner may comprise a simple tube leading from the inlet of fresh air and capped or so covered as to allow the passage of air and yet exclude the falling ashes.

The foul air from the rooms may be conducted of through foul-air Iiues in the chimney or otherwise, as may be desired.

Below the fireplace at the front I provide air-inlets at L, controlled by a suitable damper, so air may be supplied to the combustion from the room when desired.

In the operation of my invention it will be seen that the supply of air to the fire itself is taken either from below the foundation or at the foundation, or, if desired, it may be taken from the fresh-air compartment of the chimney by means of an oxygen-burner,which plan reduces the exhaustion of oxygen from the rooms of the house to the minimum and also diminishes the pressure of air from the front upon the radiation.

rlhe diaphragms, either in whole-that is,

covering the whole flue-space-or in two or more parts closing the different passages, constitute important parts of my invention. It is intended to utilize the space above the diaphragms in some cases for exhaust-fines.

It will be understood that the devices for taking in air on the Windward side may be as shown in Fig. 5 or of any other suitable construction, and I do not herein claim as my invention the specific construction of the said air-inlet devices.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a fireplace-heater an oxygen-burner composed of upper and lower sections provided with openings movable into and out of register substantially as shown and described.

2. In a iireplace-heater, an oxygen-burner comprising a lower section having a concave plate and an opening through the same, and an upper section having a convex plate and an opening through the same, and a distributer communicating with said opening, the said convex and concave plates being iitted together substantially as shown and described.

3. In a fireplace-heater, an oxygen-burner composed of a lower section and an upper sec tion movable upon said lower section and provided wth projecting arms adapted to play between the bars of the grate as said section is moved substantially as shown and described.

4. The combination of the `fireplace having a hot-air space or chamber and a flue or flues leading therefrom, the smoke-liuc leading from the fireplace, and the fresh-air flue leadin g downward along the smoke-flue and opening into the hot-air space or chamber substantially as shown and described.

5. The combination of the fireplace the hotair space or chamber, the chimney having the smoke-line leading from the fireplace, the fresh air flue leading down alongside the smoke-flue and opening into the hot-air space, such fresh-air flue being provided near the top of the chimney with weather-vane devices arranged to take in air on the Windward side substantially as shown and described.

6. In a fireplace-heater, an oxygen-burner composed of upper and lower sections one of such sections being movable with respect to the other substantially as set forth.
